Objective To evaluate the efficacy of the drug-eluting stents in the treatment of coronary artery diseases in patients with diabetes. Methods This study included a retrospective database of 600 consecutive patients with coronary artery disease who underwent drug-eluting stems implantation in Zhong Shan Hospital,including 147 pa-tients with diabetes. The MACE in this study included death of any cause,nonfatal myocardial infarction,target lesion revascularization and target vessel revascularization. All the MACE were recorded. The efficacy of the drug-eluting stents was evaluated by the incidence of MACE and the rate of in-stent restenosis. Results No significant differences were found concerning the incidence of MACE (7. 9% vs 4. 9% ,P = 0. 344) as well as the rate of ISR(6. 0% vs 4.9% ,P =0. 540) between patients with diabetes and patients without diabetes. No significant differences were found concerning the incidence of MACE(7.9% vs 4. 9% ,P = 0. 344) as well as the rate of ISR( 1.4% vs 1.9% ,P = 1. 000) between Cypher stents and TAXUS stents. Conclusion Drug-eluting stents are effective in the treatment of coronary artery disease of patients with diabetes. There was no significant difference in the rate of MACE and in-stent restenosis between the two leading drug-eluting stents of sirolimus eluting Cypher stent and the paclitaxle eluting TAX-US stent.

Objective To evaluate the incidence of contrast-induced nephropathy(CIN)in non-selected patients undergoing coronary angiography and intervention,and to investigate,the clinic risk factors of CIN as well as the renal safety of isosmolar iodixanol.Methods A total of 532 patients undergoing diagnostic coronary angiography or percutaneous coronary intervention were enrolled.Serum creatinine(SCr)was measured at any time within a week before the procedure and 2 days(48 hours)post procedure.The definition of CIN is the increase of serum creatinine of 44.2 ?mol/L(0.5 mg/dL)or 25% of the baseline at 48 hours after the use of contrast media.The effects of contrast media on renal function in patients undergoing coronary intervention were investigated and predictors of CIN were determined using logistic regression test.Results(1)Among the 532 patients,CIN occurred in 29 patients and the incidence of CIN in non-selected patients was 5.5%.(2)The incidence of CIN was significantly higher in patients with baseline eGFR

20 mm has negative correlation with restenosis.

Objective To evaluate the safety and efficacy of bone marrow cells(BMCs) transplantation on the improvement of cardiac function and myocardial perfusion in patients with old myocardial infarction. Methods and Results A total of 10 patients with anterior wall myocardial infarction were transplanted with autologous mononuclear BMCs through an infusion catheter which was placed with the tip in the left anterior descending coronary artery after coronary angiography and interventional therapy if necessary. After 3 months of follow-up, a significant increase of left ventricular ejection fraction(LVEF) determined by ultrasonic cardiography was found (54.5%?6.5% vs. 45.3%?9.8% before transplantation, P=0.003); 201-thallium scintigraphy (SPECT) showed that ventricular myocardial perfusion was significantly improved as the semiquantitative score of the immediate and delayed myocardial perfusion defects decreased from 29.5?5.8 and 28.6?6.3 to 23.9?5.7 and 23.0?6.1prospectively (both P

0.05) in the BMT group but significantly enlarged in the CON group (50.4?6.0 mm vs. 55.2?7.1 mm, P

0.05).Conclusion Aspirin plus cilostazol showed comparable antithrombotic effect as aspirin plus ticlopidine after elective coronary stenting and may serve as an alternative treatment for patients intolerable to ticlopidine.

10 mm) treated by CBA or BA were retrospectively analyzed. CBA was used in 74 patients and BA in 43 patients. Results Initial success (residual restenosis ≤30% with no major complications) was achieved in 99% of cases in CBA group and 100% in cases of BA group. Follow-up angiography was performed in all patients at (5.8?1.6) months. The diameter stenosis percent after CBA was lower and the instant gain after CBA was larger than that after BA (11.81%?9.17% versus 26.33%?10.04% and 1.96?0.51 mm versus 1.51? 0.54 mm, respectively; P

Objective To evaluate the long-term clinical outcome of percutaneous coronary intervention ( PCI) with drug-eluting stents ( DES) for distal unprotected left main coronary artery (ULMCA) lesions. Methods Between Jan 2005 and Dec 2009, 111 patients with distal ULMCA disease who underwent drug-eluting stents implantation were enrolled in this retrospective study. The primary end points were major adverse cardiac and cerebrovascular event (MACCE) at follow-up, including death, non-fatal myocardial infarction, cerebrovascular event and target lesion revascularization ( TLR) . Results Patients were 65. 6 ± 10 years old. 21. 6% were diabetic. 31. 5% of the left main bifurcations were classed as Medina 1, 1, 1. Provisional T stent technique was performed for 79. 3% of the population. 30. 6% of cases underwent angiography follow-up. The median follow-up time was 2. 3 years, the MACCE-free survival was 87. 4% and the estimated freedom from TLR was 94. 6% . Diabetes mellitus was identified as the predictor of TLR. Conclusions PCI with DES for distal ULMCA disease was safe and effective when the strategy was made based on the case-by-case assessment.

Seventy-one patients with variant angina (VA) admitted in the Cardiology Department from January 2003 to March 2011,were divided into non-stenosis group (stenosis ＜ 50％,n =43) and stenosis group (stenosis ≥50％,n =28) according to the degree of stenosis.The differences of the risk factors,clinical manifestations,electrocardiogram,echocardiogram and laboratory examinations between these two groups were compared.The average age of patients in stenosis group 58 ± 8 y was higher than that in non-stenosis group (52 ± 9 y,t =2.43,P =0.02).Other risk factors,including male gender,smoking,hypertension,diabetes mellitus and lipid disorder did not show any differences between the two groups.Percentage of patients with angina pectoris lasting less than 5 min was higher in stenosis group (x2 =5.98,P =0.02),while percentage of effort angina,seeking medical consultation ≤ 6 months of onset and hemodynamic disorders showed no difference.Laboratory examinations had no differences.It is difficult to determine whether the VA patient has fixed coronary stenosis by analyzing the risk factors,clinical manifestations and laboratory examinations; to determine the fixed coronary stenosis coronary angiography is necessary.

The design aims at improving and enriching nurturance theories and practice paradigms related with medical students' doctor-patient communicating competence.It is based on the view about cultivating and evaluating undergraduates' doctor-patient communicating competence and the theoretical basis about the existing research achievement and follows teaching practice regular pattern.Doctorpatient communicating competence of undergraduates has its own multidimensional meanings.Construction methods are as follows:taking one course as the core; enrolling multidimensional discipline in classroom teaching; combining classroom teaching with varieties of practice; establishing medical case communication training model; introducing appropriate evaluation system.Its construction principles should be found on the humanistic essence.
